With final approvals in hand, Stanford University is getting ready to start construction on its massive $5 billion hospital expansion project.

The Palo Alto City Council voted 7-0 Monday to green-light the project after a three-week delay because of concerns about construction’s impacts on a day care near the Hoover Pavilion.

Stanford agreed to delay its project while it found a new home for the Arboretum Children’s Center, which provides care for about 140 children of Stanford faculty, employees and students. The university plans to build a six-story parking garage adjacent to the day care. Arboretum parents feared the construction would threaten their children’s health and safety.

Late last month, Stanford offered to temporarily relocate the day care to a site on Stock Farm Road, between Oak Road and Campus Drive West. Hospital spokeswoman Sarah Staley said Tuesday that hospital officials are “incredibly delighted” to receive final approval for the project.

“We were in constant communication with (parents) to make sure we understood fully their concerns, their requests for further information,” Staley said. “We’re glad to say that we came up with a solution that works well for them, will work well for the children, most importantly, and will also allow our projects to move forward.”

Arboretum parent Simon Klemperer said in an email to The Daily News that the resolution shows “the high level of concern at Stanford, and their determination to do the right thing.”

Still, some worries remain for parents. At the Palo Alto City Council meeting Monday, parent Jeff Shrager said he is still concerned that some work will begin at the nearby Hoover Pavilion building before the center can be moved, which could take about six months.

The first projects, which will likely start next month, include interior renovations to the Hoover Pavilion building and utilities work on Welch Road.

“Come mid-August you’ll start to see wheels down and mobilization occur,” Staley said.
